I woke on day and brain had changed. 25 years years later and an unrelated MRI it was discovered I had a frontal lob cavernoma. But it was very small and some experts say incidental, other so no it is causing your problems. But this aside I know my memory is getting worse and it has been for the last 25 years. Has anyone had a worsening of their cognitive functioning with no known cause? The cavernoma shouldn't be doing this, its stable.
However did you go about proving it was bad? Has anyone had a working MRI? Or one of the more powerful scanning procedures that has exposed the true extend of their problem? Cheers
